After viewing countless posts of anonymous users being trolls for red thumbs. I got a brilliant idea.
Funnyjunk keeps track of what IP address you are signed into.
DJ 4dm1n should code the site to where the IP address of anonymous posts are tracked and the next user to sign into that IP address gets cock slapped with the red thumbs from the post.
Could also be beneficial to users who forget to log in and miss out on greens.
